Centrifugal Pumps Self-priming, segmental type TKH 6501 . . . 15306 TLH 15101 . . . 15105 133.81101.55.01 E PUMP TECHNOLOGY TKH/TLH PIII/6 83101 08/91 TECHNICAL DATA Capacity: max. 350 m³/h Head: max. 185 m Speed: max. 3600 rpm for THK max. 1700 rpm for TLH Temperature: max. 60 °C for TKH max. 120 °C for TLH Casing pressure: max. PN 16 Shaft sealing: stuffing box or standard mechanical seal Flange connections: DIN 2501 PN 10/16 SIHI-standard, resp. Sense of rotation: clockwise when looking at the pump from the drive end APPLICATION The self-priming centrifugal pumps of series TKH/TLH are used, when clear or turbid liquids, free from solid particles, are to be handled reliably and trouble-free. Because of their self-priming capability and owing to the multitude of material combinations, the pumps cover a wide range of applications in such fields as: the supply of drinking and utility water for greater communities and large industrial plants, the handling of fuel in decanting stations, and large tank plants the construction of fire-extinguishing equipment, the construction of cooling plants, shipbuilding (ballast and stripping pumps), the chemical industry and the petrochemistry DESIGN Horizontal, segmental type centrifugal pumps with shrouded impellers and a priming stage arranged on the suction side. The priming stage runs in parallel with the first liquid stage and operates acc. to the mixed media separation principle during the priming phase and in case of big gas portions.. As result of the separation of the gas before entering the first impeller this is largely admitted with liquid. Finely divided gas portions can be handled without problems. If during the priming cycle, the counter pressure on the discharge side is below 0,5 bar, the pumped-away gas is discharged into the delivery pipeline. If the counter pressure is higher than 0,5 bar, then a separate gas discharging device is required. More detailed information can be obtained from Appendix TH - KS. The programme includes 7 pump sizes ranging from one stage to a maximum number of 9.

Discharge orifice arranged radially upwards. Series TKH 8300 to 15300 Suction and discharge orifices and TLH 15100: showing radially upwards. Flanges: The flanges are in compliance with DIN 2535/ PN 16. Exception DN 200 (on the suction side of pump size TKH 15300) complying with DIN 2532 / PN 10 and DN 80 designed according to manufacturer’s standard. The flanges are either grooved according to DIN 2512 or drilled according to ANSI 150 for all nominal widths. Flanges according to ANSI 300 can be supplied for nominal width DN 80 and according to BS, table F for nominal widths up to DN 100. Bearings: Two grease-lubricated deep-groove ball bearings according to DIN 625. The first charge of grease being applied in the factory Designation of this construction type: B. Sense of rotation: Clockwise when looking at the pump from the drive end. Designation of this construction type: .N Shaft sealing: The sealing of the shaft passage mentioned on page 2 can, according to choice, be effected by a stuffing box or a standard mechanical seal:
